I want to know call barring password


a sim card or phone needs a puk code or is locked BECAUSE it is not active,in order to unlock a sim card,you need to either,pay the balance owed,buy a new monthly service,open a new contract with a cell service or return the sim card to whom it belongs to,we at fixya CANNOT GIVE YOU A NUMBER TO UNLOCK YOUR SIM CARD,there is a reason why it is locked,if it was easy to get a code,then anyone could steal your phone and use it and you couldnt stop its use for at least a month.
a phone is jail broken when you alter it to work on a different cell service provider,we at fixya do not jailbreak anything,if it isn't legal,then it doesn't belong here.

My phone says it has no service. How can I fix this?


Hi Cgsaiki,

Please check if you have a good cell coverage at the area from your provider. If the service was just working ok until now at the area.

Tried to remove the battery and un-seat and re-seat the sim card from the card bay on your cellphone. If its still not working, try to change the sim card itself with a confirm working one.

If the new card still work on your cell, you need to replace the sim. If the confirmed working sim card is also not working on your cell. you might want to have your cell check by the provider/manufacturer as as there is something wrong either with the contact of the card bay, the sim card reader itself, or the cellphone's transceivers is acting-up.

Hope this helps.

I had bought nokia E71 from nokia store and now after 1 odd month it has started showing sim card registration failed followed by insert sim card message on white screen...what could be the problem and i...


Sim card registration failure means that the card in the phone is not being recognized by the service provider as a valid or current account. The service provider is denying service based on the sim card that you are trying to use in your phone. If you have a current and valid account with your cell phone provider then you need to contact them to remedy the problem because something in the registration process has failed. They need to update and/or correct their records to link your account to the sim card in your phone so that your service will work.

I bought a prepaid phone card for my lg cookie and it will not let me add it i called at&t and they did something and made my phone not have a number and now it says i do not have a sims card too what...


if you are using a sim card from a prepaid phone just bought, and then add it to another att branded phone, it will not work. if you use the sim card in the new prepaid phone, it will work. att locks the sims from working in other phones for 3 months from the factory. i did the same thing with a prepaid phone and a Q9, put the sim in the q9 and it said, no service. put the sim in the prepaid phone, it worked fine. my suggestion is to talk nice ot the att store employee, and they will give you a new sim.

let me know if your phone is doing something different.

I have a few cell phones that used be with Tmobile, ATT, and Alltel. I've seen ads that say buy a Motorola sim card for unlimited everything $50. If I put that simcard in my Motorola Razor would it work...


If the handset isn't locked to those three networks i.e. Tmobile, ATT and Alltel, then any sim card will work. Almost all handsets are locked to certain networks and so we can't use sim cards of other networks. You can verify this in only one way. If you have a sim card of another network (in your hand at the moment or you can borrow it from your friend or from other family members), you can insert the sim card, suppose a Verizon sim card, not those three. If the verizon works, then all sim cards should work on your handset.

Since your phone already works with Tmovile, ATT and Alltel, I hope all other network sim cards should work without any problem. Suppose if a phone is locked to network means, it's locked by the Service Operator to preserve their customers so that the customers will return to them if anything happens with the sim card or with the phone, this is a business plan logically designed.

For now, I can't confirm you, but at least if you could try with another sim card of another network (verizon) and it works, the no doubt, all sim cards should definitely work. But if you can't try it that way, I wouldn't recommend you, until you get it tested.
And that Advertisements seems a kind of something, "....unlimited everything...." sounds good, but must be unlimited Incoming Call and could also be without monthly rental fees. I don't recommend unless you ask about it to someone who already used the same sim card ($50). As we know, advertisement is advertisement.

If you need further help, let me know.

Good luck.

Thanks for using FixYa.

Master code for all nokia 3110


Nokia Unlock Codes, Nokia Phone 3110 Secret Codes, Cell Phone Codes

Nokia 3110 Secrets

*#06# : Checking the IMEI (International Mobile Equipment Identity)

*#7780# Restores Factory Settings (Memory, language, counters are not included).

*#3110# : Checking the phone's software (SW) - Also called "Firmware Revision Information".

*#746025625# [*#sim0clock#]
Checks if the SIM clock can be stopped. SIM clock stop is a kind of stand-by mode which will save battery time. This code doesn't work with software version 4.59.

*#92702689# [*#war0anty#]
Press the following warranty code :
6232 (OK) : Displays the Month and Year of Manufacture (0997)
7332 (OK) : Displays the date of the last repair - if found ('DATE NOT SAVED'...)
7832 (OK) : Displays (if found) the date where the phone was purchased ('DATE NOT SAVED'...)
9268 (OK) : Displays Serial Number
37832 (OK) : Set the Purchasing Date MMYY
(Warning : You can only set this once.)
87267 (OK) : Transfers ALL phone numbers, pictures, sounds from one phone to another

Service Prover Lock
The service provider (SP) lock is used to lock the cell phone to the SP's SIM card. Once the cell phone is locked to a specific operator, if one inserts a SIM card from a different operator the phone will refuse to accept it. The cell phone will however accept another SIM card from the same operator. All Nokia phones (2110 and newer) have four different SIM locks which can be used to lock the phone for up to 4 different providers. But most phones with restriction only have one lock activated. (Lock 1) The main code used in Nokia phones is:
#pw+(master code)+Y#

This code is able to check, activate or remove SIM card restriction (SP-lock).
Use the * key to get the p, + and w chars.
'Y' has to be 1,2,3 or 4 - depending of what lock you what to deal with.

#pw+1234567890+1# for Provider-Lock status
#pw+1234567890+2# for Network-Lock status
#pw+1234567890+3# for Country-Lock status
#pw+1234567890+4# for SimCard-Lock status # = DOUBLE-CROSS
W = PRESS "*" THREE TIMES
P = PRESS "*" FOUR TIMES
+ = PRESS "*" TWO TIMES
MASTERCODE = 1234567890
Y = NUMBER 1 TO 4 [Master Code] is a 10 digit code, based on the phones IMEI number.
[ No requests for the "Master Code" will be entertained. ]

Eg. To remove restriction on Lock 1 type following code:

#pw+(master code)+1#
If you just want to check your phone use 10 random numbers Eg. 1234567890 as the (master code)
eg. To check if phone if restricted on lock 1 type the following code:
#pw+1234567890+1#

NOTE : These codes could be used with care. A user told me that it's only possible to type in about 3 different codes on each lock! Then something bad will happen ..therefore be careful!

Bypass the SP lock
With a Nokia 16xx/21xx/31xx/51xx/81xx that are SIM locked to one provider you can bypass the SP lock like this:
1: Insert sim card of different provider.
2: Turn on the phone and press the UP VOLUME key for 3 sec. then release it and the phone says PIN CODE?
3: Press the "C" key.
4: Then Press * and wait until it disappears and appears again, then press * one more time and 04*PIN*PIN*PIN#


The phone should now say : PIN CODE CHANGED (or ACCEPTED) and the SIM card is accepted until you restart the phone again.
NOTE: On version 5.04 Nokia has removed this option.

Fast silent mode
In the newer versions (v.7.11 or higher) a quick silent mode can by entered. Press Menu then #.

The 54# Tip:
Type 1#, 2#........54# on the keypad (when you're not in the menu) to get the phone number used for with this key when speed

Sim card rejected


You need to do some testing first.

Put your sim card on another phone (should be unlocked or the same provider) and see it it works.

Put another sim card on your phone (should be the same provider sim) and see if it works.

From there you can check where the problem lies.

SIM card registration failed


You might have filled up the memory to the brim and the phone doesn't have enough to switch on.
Try reformat to original settings. anything you stored on the phone will be lost.

How to reformat your phone, first turn it OFF. Press * 3 send at the same time and keep them pressed while you turn the phone on.
Give it time to work.

Remember, do not let go the 3 keys until you see the formatting screen.
After a few minutes when the process is over, your Nokia N70 will be back to the original delivered system.
